Create a strong, long-lasting waterproof roof with our range of Flat Roof GRP products, ideal for garages, extensions and outbuildings. GRP (glass reinforced plastic) roofing systems are a popular choice for flat roofs thanks to their durable, seamless finish and excellent resistance to weathering. Whether you’re installing a new flat roof or repairing an existing one, GRP materials help provide reliable protection against leaks and standing water when installed correctly.
Flat roof GRP is commonly used for garage roofs, dormers, balconies, porches and flat roof extensions, offering a tough surface that performs well year-round. GRP roofing creates a fibreglass layer that forms a strong waterproof barrier, helping extend roof lifespan and reduce maintenance compared to some traditional materials. Using compatible trims, resins and topcoats is essential to achieve a neat edge finish and consistent long-term performance.
For best results, ensure the roof deck is properly prepared, follow correct application steps for resin and matting, and allow full curing time before exposure to heavy weather. Good installation is key to achieving a durable, watertight finish.
